1. Why the Solar Industry Is Its Own Worst Enemy (SCTY,
VSLR)
The U.S. solar industry's growth over the past five years is nothing short of amazing. In 2009, 382
megawatts of solar were installed in the U.S. and in 2014 that figure had grown 1,500% to 6,201
megawatts.

Companies like SolarCity (NASDAQ: SCTY ) , Vivint Solar (NYSE: VSLR ) , and SunPower
(NASDAQ: SPWR ) can now build and finance residential solar systems (which are even more
expensive than larger systems), and they can sell them to homeowners for less than the cost of
electricity from the utility.
All of this growth is great and it has been a great two-year run for solar investors, but there's a big
cloud on the solar industry's horizon that's made worse by too much success.

Subsidies and solar
The solar industry has long been assisted by subsidies, which have ranged from feed-in tariffs to tax
subsidies in different countries around the world. In the U.S., the 30% investment tax credit, or ITC,
is the industry's largest subsidy and when combined with other tax benefits like accelerated
depreciation can effectively pay for about half of a solar system's cost in the first year.
For companies like SolarCity and Vivint Solar, the expiration of the ITC could be devastating.
They're not only totally reliant in the U.S. market for demand, they benefit even more than most by
receiving the ITC tax benefits at a system's value, not just their cost, something that's been brought
up before Congress and is being looked into by the U.S. Department of Treasury.
The question facing installers today is: With the industry growing like a weed, what reason does the
government have for extending tax subsidies?

2. Falling subsidies is a story we've seen before
The U.S. isn't the first country to face this dilemma. Germany's feed-in tariff drove the growth of
solar in the 2000s and had to be lowered regularly because installations would skyrocket as costs
fell and investing in solar projects became more practical. Between 2008-2014, Germany's feed-in
tariff rate dropped about 80% and yet the industry survived. Even in the U.S. we've seen the
reduction or expiration of subsidies from New Jersey to California in recent years, yet installations
continue to grow.
Even the wind industry has seen the expiration of the production tax credit, which subsidized wind
electricity generation by paying plant owners for each kW-hr of energy they produced.
If the ITC falls to 10% for commercial project owners and is eliminated for homeowners, as the
current law states, the industry will adapt and adjust like it has in the past. But it's ironic that the
growth and financial success of the solar industry in the past few years has undercut the argument
that it needs subsidy help at all. In that way, the solar industry has been its own worst enemy.
What's likely to happen
There will be a lot of debate about the ITC in the next two years from both those who want to keep it
and those who want it eliminated. The solar industry's growth may make it hard to keep the subsidy
as it's written today, but there is some good news. The growing number of states that are building
significant solar industries and employing thousands of workers in the process may make it
politically possible to replace the ITC with a reduced tax credit or some other form of subsidy.
The political reality is that there's widespread support for solar around the country, so if it came
down to a debate over outright elimination of the ITC it could be politically detrimental to fight
extension. But it also doesn't make much economic sense for the government to subsidize an
industry that can support itself without subsidies, or at least on lower subsidies.
A logical resolution would be to agree on a temporary lower subsidy like a 15% ITC for two or three
years that would be phased out in exchange for consistent rules giving solar access to the grid. One
of the ways utilities are fighting solar today is by challenging net metering and changing their fee
structure to undercut competition from solar energy, so setting a level playing field across the
country may be something the industry would accept as a compromise.
The debate will be one that has a huge impact on all solar installers in the U.S., so it's worth
watching for investors. Just keep in mind that subsidies have helped fuel growth and success may be
the very reason lawmakers will end subsidies for solar.

3. This $19 trillion industry could destroy the Internet
One bleeding-edge technology is about to put the World Wide Web to bed. And if you act right away,
it could make you wildly rich. Experts are calling it the single largest business opportunity in the
history of capitalism... The Economist is calling it "transformative"... But you'll probably just call it
"how I made my millions." Don't be too late to the party -- click here for one stock to own when the
Web goes dark.
